Application filed March 8. 1909. Serial No. 481,931.

To all whom. it may concern:

Be it known that I. llAItltY X. CUVELL. a Q citizen of the UnitedStates. and a resident l tight door 4 arran ed to aflord easy access 55to the interior of the housing or casing. A vertical shaft com weed oftwo sections 5 and 5 extends through the casing, the

f winch head 1 being keyed, or otherwise se- 3 cured to the. upper endof shaft 5. Atthe designed for use on the deck of a ship where j it. iscustomary to have a number of winches which may all he in usesimultaneously, butwhich are more usually operated one or two or more ata time; in such cases it is desired that the heads of winches not in usebe stationary, and it is provided by my invention that the winch isnormally nun operating and the brake applied, operation being secured bythe movement of a lever and being chccltetl automatically when the lexeris released.

In the drawings herewith I have shown and will hereafter describe areferred form of my invention as emboied in a vertical winch especiallyada-ited for use n board a ship, but I do not csire to limit myself tosuch particular form or use but to cover any form of embodiment of myinvention which consists in the arrangement, construction and operationof parts as set forth in and falling within the scope of the claimshereto appended.

Like characters of reference denote like arts in all the figures of thedrawings ierewith.

Figure 1 represents a sectional side view in vertical elevation of thepreferred form of my improved winch; Fig. 2 represents a side view inelevation,- a side of the winch housin or casing being removed andportions the niechanisni therein being shown in section; Fig. 3represents a plan view taken throu h the winch housing or casing,1ileegrtain hldtfill parts being shown in broken es. The preferred formof construction of my improved winch in detail is as follows: The winchhead 1 is mounted on the top of a metll housing or casing 2, which 1ssecured to a deck plate or other suitable support 3, end is providedwith a water- 'tained in a timid position.

60 top of easing 2 the shaft section 5 passes through a bearing formedby casting Q,

which is preferably bahhitt lined or hushed.

To the l0\\'t-l' end of the shaft section 5 is key d. or otherwisesecured, a metal disk 7. to the peripherv of which are bolted m'etallit:friction blot-ks 8, preferably formed "in M'glllt'nts and rhamfered orbeveled at their lower outer edg s to form a suitable friction surface.he hub of the disk projects beyond the. lower end of the. shaft 5 toprovide. a seat to receive the. upper end of the shaft section 5, inwhich hub or seat, the latter hait turns when the disk 7 is at restasher inafter set forth. all as shown at 231. metal rin; 5 is bolted todisk 7 extending: outward from the edge thereof and serving to take theshear or strain from the bolts whit-h secure the friction blocks 8 inplace. metal di k 10 is mounted adjac nt the upper end of shaft section5 being adapted to rotate with the shaft and. capable of \Plllmtladjustment thereon by 11"?! of a feather on tile rllitl l; tln dink 10is adapted to be in frictional engagement with friction blocks 8 whenmoved upward into contact therewith. At the bottom of the casing 2 shaftsection 5' passes through a bearing (3 bolted to the casin and preferably babbitt lined. A drive shift 11 untlerncath the deck I} isconnected with and adapted to drive the shaft section 5 through bevelgears 12. At the bottom of easing 2 around the shaft .7 is placed a ringor cam. member 13 formed with an inclined ll))01 surface; said cammember being capa he of movement around the shaft but normally main- Asecond ring or cam member 14 with an inclined under surface rests uponcam member 13, being capable of movement around the shaft, am

when so turned, riding on cam 13 and being elevated or lowered inaccordance with the direction in which it is turned.

Outside of the casingl is located a foot: lever 15 secured to ahorizontal shaft 16 which extends through the side of the cusing. Aertical shaft 17 within the casing rests in lower and upper bearings l8and 19, and is rotated by movement of the foot levcr l through thelTlQSllillQ' l)(\'l gear segments it! and "it secured to shafts it, aml17 respectively. lever arm '1'. is secured to the shaft 17 and a leverarm '13 to the cam member H: joining levers and 2 3 and pivotallvsecured to each is a connectin; link ".34. spiral spring secured to thebottom of the. casing 2' and to cum member l4. serves to ilot'ttiallretain .-aid member in its lowered position.

adjust ng arm 26 is pivotally secured toa lever arm projecting from thecam member 13, the nrm 2o passing through a flange and being adjusted inposition b a boltthreaded upon its free end: by the adjustment of thearm .26 the cam member I3 i turned to give the desired elevation to thecam mer't r 1 when the latter rides upon the member 13; wea of thefriction faces beim; thus compensated for and the cam member 13 beingheld in any desired fixed position.

spiral spring 27 between disks 1' and lb normally throws the disksapartand keeps the friction surfaces out of engagetuent.

Secured to the top of shaft- 17 is a brake toggle secured to which andadjustable by means of bolt 29 is a brake band Ito which encircles theupper portion of the per phery of the friction blocks The brake band 3t)is normally held in braking engagement with the blocks 8 by n'ieans ofthe spa-in; 2.. through its action on cam member H. which is connectedto the shaft l? to which the surfaces are held out of engagenu-nt. bythe action of spring 27, cam member l-l being held in its loweredposition by spring 25 which also servcs to hold the brake band 30 inengagement with friction blocks 8, the

shaft section 5 remaining stationanv and shaftsection 5 revolving,if'power is applied to the shaft ll. \Vhcn itis desired to operate thewinch head the foot lever 15 is depressed, releasing the brake 3t) andturning the cam member it against the action of spring 25, cam member Itriding on the cam member 13 and being elevated thus forcing dish 10 upinto frictional engagement with the blocks 8 against the action of thespring 27; the operation of the winch head being thereby secured. Uponreleasing foot.

friction surfaoes separated, and brake applied automatically andoperation of the. winch head ceases.

As above described it will be seen that l have provided a winch of noveldesign normally stationary, readily operated b the op eration of alever, and automatically broug it to rest upon the release of the lever.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent: is:
